A rope consisting essentially of a plurality of interengaged strands which are plaited together; each of said strands including a plurality of fibers and a tubular braided cover of textile material surrounding the fibers to maintain the integrity of the strand, a length of the strand being at least 99 percent of the length of the major portion of the fibers therewithin, the weight of the tubular braided cover being no greater than about 20 percent of the combined weight of the cover and the fibers.
Claim 7
Dependent Claim
31 words
A rope according to claim 4 wherein there are only four pairs of strands with the strands in each pair running together and being plaited to the other pairs of strands.
Claim 8
Dependent Claim
20 words
A rope according to claim 5 wherein at least some of said strands have an electrical conductor extending longitudinally therewithin.
Claim 9
Dependent Claim
97 words
A rope comprising four pairs of strands engaged by having the strands in each pair running together and being plaited to the other pairs of strands, each of said strands being formed of a plurality of core yarns and a cover, said core yarns being substantially parallel to the axis of their respective strand, and each said cover being a tubular cover of textile yarns braided together to surround the core yarns of the respective strand, the weight of said cover being no greater than about 20% of the combined weight of the core yarns and cover.
Claim 10
Dependent Claim
97 words
A rope comprising four pairs of strands engaged by having the strands in each pair running together and being plaited to the other pairs of strands, each of said strands being formed of a plurality of core yarns and a cover, said core yarns being substantially parallel to the axis of their respective strand, and each said cover being a tubular cover of textile yarns braided together to surround the core yarns of the respective strand, the weight of said cover being no greater than about 20% of the combined weight of the core yarns and cover.
Claim 11
Dependent Claim
117 words
A rope having low elongation characteristics for transmission of electrical signals, said rope comprising a plurality of strands, each of said strands being formed of a plurality of core yarns enclosed within a tubular braided cover of textile fibers, a major portion of the core yarns in the strand lying substantially parallel to the longitudinal axis of the cover to impart low elongation characteristics to the strand, at least some of said strands including an electrical conductor which extends longitudinally therewithin parallel to the core yarns whereby the braided cover positively contains the electrical conductor and prevents its From popping out to the surface of the rope, said strands being plaited together to form the rope structure.
